There is just something about bladed weapons that naturally draws people to them. Maybe it's the brilliant shine a well-polished blade gives or maybe it's the hundreds upon hundreds of intricately designed swords, knives, and other blades that exist around the world. Whatever the reason, this character has a keen interest in blades. They can tell the difference between every weapon in their collection no matter how small. They love knives so much they can't but gush about them to anyone who would hear. Blade enthusiasts love the danger and morbidity associated with knives so quite a few of them double as Nightmare Fetishists or Psycho Knife Nuts.
Some collectors only collect knives and other blades for show and never intend to use them as weapons, while others carry hundreds of knives on their person at all times.
The blade enthusiast's collection might be mounted on a Wall of Weapons.
Subtrope of Otaku. See also Gun Nut, which is for gun enthusiasts. For characters who primarily use knives or other bladed weapons that reflect their personality, see Weapon-Based Characterization.
For characters who collect unorthodox items, see Collector of the Strange.
